RealProducer® 11.0 Beta 2 Release Notes
Date: Tue, Jun 14, 2005
RealProducer 11 converts a wide variety of audio and video files into the
RealAudio and RealVideo format. RealProducer 11 also allows you to capture audio
and video from live sources such as a camera or microphone and broadcast a live
stream via a Helix Server. The software and documentation are provided to you
in accordance with your license agreement.

1.1 New Features in Producer 11
Live Low Latency
Configurable Maximum Packet Size
Improved Firewall Traversal
.RA and .RV file extensions
See the RealProducer User's Guide or the included help files for more
information about these new features.
1.2 Known Issues in this Beta Release
The following is a list of hints and known issues to be aware of with this Beta
release of RealProducer.
In order to take advantage of the new Live Low Latency feature in RealProducer
11, you must be broadcasting to a Helix Server 11. If you are broadcasting to an
older server with Latency Mode set to anything other than 0, the server will
report Malformed Packet messages to the server logs, and clients will not be
able to connect to the broadcast.
The Legacy Push broadcast method has been removed from RealProducer 11. This
means that you cannot broadcast to a Pre-8.0 RealServer from RealProducer 11.
When performing an encode, RealProducer will print out a number of invalid
warning messages about invalid audiences. These messages can be ignored. An
example message is:
Warning: The requested presentation type is audio-only, while the source
supports video. Unable to use this audience for the presentation.

3 System Requirements
3.1 Application System Requirements
Operating System
Windows 2000, and XP1,2
Linux 2.4 with Glibc 2.1 or greater, Linux 2.6
Any distribution that meets the above requirements should work but the following
are tested and supported:
RedHat 9
Suse 9
Hardware
Minimum3
500 MHz CPU
128 MB RAM
Recommended4
2.4 GHz or faster Pentium IV
512 MB RAM
Windows XP recommended for Hyperthreading support.
Latest Windows Service Pack recommended for any Windows version.
Minimum system configuration can encode using the command line application into
RealVideo 10 in High Complexity Mode from a live device at 240x180 @ 15fps to a
28 kbps and 56 kbps SureStream file (default settings) without any degradation
in encoding complexity or frame rate.
Recommended system configuration can encode using the command line application
into RealVideo 10 in High Complexity Mode from a live device at 320x240 @ 30fps
to a 768 kbps file without any degradation in encoding complexity or frame rate.
3.2 Supported Chipset Optimizations
Below is a list of CPU optimizations that are supported by RealProducer.
Consult your hardware vendor's documentation to determine if your hardware
supports these optimization instruction sets.
PC (Intel, AMD, etc)
MMX (400% over non-MMX systems)
SSE1 (No performance increase)
SSE2 (20% speed-up on top of MMX)
SSE3 (6-7% speed-up on top of SSE2)
Hyperthreading (0-20% speed-up on top of MMX/SSE2/SSE3)[1]
Mac (G4, G5)
Altivec (300% performance increase)
1. About Hyperthreading and RealProducer
Hyperthreading can be run with most versions of Windows by only recommended for
use with Windows XP.
Windows 2000 and NT do not distinguish between virtual and physical CPUs and
thus will not guarantee that two CPU-intensive processes are not run on the same
physical CPU. Older versions of Windows do not support multiple processors.
Hyperthreading may not yield a significant improvement with cache-intensive
processes like RealProducer unless the CPU cache is large enough.
RealVideo codecs require large CPU caches. When hyperthreading is used, this
doubles the cache size requirement. Generally only Intel "Prescott" or later
have sufficiently large on-board caches to yield a performance improvement with
cache-intensive processes like RealProducer. If the cache size is not large
enough, enabling hyperthreading will not degrade performance but no improvement
in performance will be observed either. With large enough CPU caches, a 20-25%
performance improvement should be observed.
3.3 Supported Input File Formats
File type support varies by platform. The following list describes the input
file types supported and the platforms they are supported on:
Linux
Uncompressed AVI
Uncompressed MOV
Uncompressed WAV
Mac OS X
Uncompressed MOV
Uncompressed WAV
Windows
All uncompressed file formats listed above
Any compressed and uncompressed file types supported by DirectShow (e.g.
compressed AVI, MPEG1, MPEG2, MPEG4, AU and AIFF)
Any compressed and uncompressed file types supported by QuickTime (e.g.
compressed QT, MPEG1, MPEG2, MPEG4, AU and AIFF)
Notes:
For MPEG2 input support via DirectShow, an MPEG2 decoder, commonly installed by
PC DVD Players, is required.
DirectShow file reader supported only on Windows.
QuickTime file reader support requires QT 5 Player or later and is supported
only on Windows.
3.4 Supported Input Capture Devices
General Requirements
Card must support one of the color formats supported by RealProducer (See below)
Card should support hardware scaling (if not, use RealProducer to resize - not
hardware drivers)
Windows
Audio: Wav or WDM-based capture device (WDM recommended)
Video: VFW or WDM capture device (WDM recommended)
Linux
Audio: OSS-based capture device (ALSA may work in in OSS-compatibility mode but
not supported yet)
Video: Video4Linux 1 capture device (Video4Linux 2 may work but not supported)
Mac
Capture no supported
3.5 Supported Input Color Formats
YUV12 (a.k.a. I420)
RGB 15, 16, 24, 322
BGR 15, 16, 24, 32 (Macintosh versions of RGB)
Windows YUV Formats: YUY2, YV12, YVU9, YVYU, CYUV, IYUV, UYNV, UYVY, V422, YUNV,
Mac YUV Formats: 2VUY, YUVS, YVYU, YUVU, YVU9, YUV2, V210
Note: I420 is the native color format required by RealVideo codecs. Using I420
as input will improve performance by removing the need to convert the color
format prior to encoding.
